Application filed October 16, 1920.

f To all Ptai/tom` it may cof/wem on, and which shall also facilitate the removal of the tire therefrom.

Heretofore automobile Wheels have been constructed with valve-receiving openings in some portion of the felloe and rim, which were ordinarily but little larger than the diameter of the valve-stein. Such a con struction introduced some diiliculty in placing a tire upon the Wheel, or in .removing it therefrom, because of the` fact that in order to dispose a tire thereon the valve- Vstem must necessarily be placed in the opening and the tube to which it is secured must `be distorted in order to permit o-f forcing the remaining portion of the tire about the Wheel. In removing a tire from this type of Wheel the tube to Which the valve is secured .must be either greatly distorted in removing the remote portions ofthe tire or the valve-stein must be forced out of the opening before commencing to remove the tire. Either method is undesirable because of the danger of ruining the tube or casing to Which the valve-stem is secured.

One object of my invention, therefore, resides in the construction of a Wheel Which shall provide for suficient movement of the valve-stem to materially facilitate the removal of the tire from the Wheel, upon which it has been disposed, Without undue distortion of the tube to Which the valve is secured.

Another object of my invention is to construct a. Wheel having an enlarged valvereceiving opening which Will not affect the mechanical strength of the Wheel to any material extent and which Will greatly facilitate the mounting and removal of a tire there from.

With these and other objects in view my invention Will be more fully described, illus- Serial No. L.iV/,355.

trated in the drawings, in which like numerals indicate like parts, and then more fully pointed out in the claims.

ln the drawings: Fig. l is a perspective view of a portion of the felloe. and rim of an automobile wheel constructed in accordance with my invention.

Fig. 2 is a transverse sectional view taken on the line lI-Il of Fig. l.

Fig. 3 is a plan view of a portion of a vehicle vWheel illustrating a modification of my invention.

Fig. t is a sectional View taken on the line IV-IV of Fig. 3.

n practicing my invention, I .propose to construct a vehicle Wheel with a valve-receiving opening communicating With a plurality of slots so shaped as to permit the valve-stem of the tire to be disposed at an angle in the opening when the tire is being mounted upon the Wheel. The same principle obtains in the removal of the tire from the Wheel in that a limited movement of the valve-stein is permitted by the particular shape of the slots communicating with the valve-receiving opening formed in the Wheel.

Although my invention is particularly adapted for application to detachable or demountable truck tire rims, it Will be appreciated from the following description that it may be applied With equal advantage to various types of Wheels.

In Figs. l and 2 is shown a felloe l, of a Wooden truck Wheel having a rim 2 mounted thereon that comprises a. base member and a pair of flange rings 2a, one of Which is removably held in place by a split ring 2l of conventional design. The felloe l and the rim base 2 are provided with an L-shaped slot 3 containing a valvereceiving opening 4. The-slot 3 is of varying depth, as indi cated by the broken lines 5 in Fig. l and as clearly shown in Fig. 2.

It will be appreciated that the particular type of slot formed in lthe Wheel shown in Figs. l and 2 permits of the ready disposal of a tire upon the Wheel because the valvestem may be disposed at an angle in the portion of the slot which extends transversely with respect to the circumference of the Wheel. Vhile the valve-stem is disposed at an angle in the slot, the remaining portions of the tire may be forced upon the rim, which operation will, of course, force the valve-stem into the central valve-receiving opening il. The particular shape of slot also permits oi en easy removal oi? the tire because the portion ot the slot that extends ciroumierentielly. with respect to the rim permits of e limited movement of the tire in e circumferential direction, which is requently necessary in order to loosen the-.tire end facilitate its removal.

In Figs. 3 end l is shown e 'lV-shaped slot in which the heed portion 5 thereof extends ine vcircuiniferentiel direction with respect to Ahe rim, and the stein 7 'thereof extends toiverd the edge ol1 the rim, or transversely 'Witlr respect to the circumference, The vulve-receiving opening is, of course, loeuted et the junction of the sererel communicating slots and the formation is developed by merely providing the L-shnped slot, shown in Figs. l end 2, with :mother slot extending` eireumiperentielly with respect to the rim. rihis lnoditiczrtion oi" my invention `possesses the seine advantages that reside in the construction shown in Figs. l end 2, with the added feature olfe eter permissible movement oi the valve-stein in e circumferential direction du "ing the reinovel oi e tire from the rim.

, it. will be appreciated that my invention is particularly adopted tothe construction oiv truck `wheels heee-use of' the 'tec-t that the pneuinetie tires employed .thereon ere ordinarily of relatively large site and ere, theretore7 more dii'iicult to handle than the pneuinetio tires oit passenger machines. It is consequently en advantage to employ e constructionthzit materially facilitates the disposal of :i tire upon the Wheel, or its removal thereirorn.

My invention muy else be employed to edventnge in the construction of Wheels 'for passenger cars.

Although l lieve shown end described :in automobile Wheel that may be constructed in accordance with my invention, sind set forth several modiiicetions that may be practiced ineen/ii in :iccordsnce therewith, it is obvious the-.t minor chang' 1meyl "nede in the particular construction 'thereof vvithont departing Yfrom the spirit or scope. or my invention, und l desire, therefore, that no limitations shall be imposed except such' es are indicated in the appended claims,

What l claim is:
